Add XMP MetaData to JPG or TIFF

See more XMP Examples

Demonstrates how to add XMP metadata to a JPG or TIFF image that doesn't already have XMP metadata. C#

bool success = false;

// This example assumes the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

Chilkat.Xmp xmp = new Chilkat.Xmp();

Chilkat.Xml xml = null;

// The first step is to create a new XMP document, which is nothing
// more than XML.  The NewXmp method returns an XML document with
// the standard XMP boilerplate.  
xml = xmp.NewXmp();

// Add some properties...
success = xmp.AddSimpleStr(xml,"Iptc4xmpCore:Chilkat","Blah blah");
// If you wish to view the XML, save it to a file and review it
// with a text editor:
success = xml.SaveXml("newXmp.xml");
if (success != true) {
    Debug.WriteLine(xml.LastErrorText);
    return;
}

// To add the XMP to the JPG (or TIFF), simply load the JPG,
// append the XMP, and save:
success = xmp.LoadAppFile("scream.jpg");
if (success != true) {
    Debug.WriteLine(xmp.LastErrorText);
    return;
}

success = xmp.Append(xml);
if (success != true) {
    Debug.WriteLine(xmp.LastErrorText);
    return;
}

success = xmp.SaveAppFile("screamOut.jpg");
if (success != true) {
    Debug.WriteLine(xmp.LastErrorText);
    return;
}
